I have problem with my water level sensor of washing machine. Its connector corroded at its center terminal.
- Is it true that the corrosion will only occur on the terminal that have negative polarity?
- How to prevent this corrosion?
- Can you explain more about this?

The corrosion looks like a Copper Salt (Like Copper Chloride). This type of corrosion will only happen in the presence of moisture and a DC current and generally on the negative terminal. (electrolysis) To prevent it, you need to prevent the moisture getting to the connector. This can be done using a plastic tube around the connector with cable ties and some desiccant. You can clean up the damage with some emery paper and methylated spirits. Then give it a spray with a contact cleaner (or WD40) to help displace any remaining moisture.
